il IGE- WILLIAM MAC LARDY AND JOSEPH LEVIS, OF' MANCHESTER, ENGLAND.

LIVE-SPINDLE AND FLIER.

Specification of Letters Patent No. 6,572, dated July 3, 1849.

To all whom it may concern Be it known that we, VILLIAM MAC LARDY andJOSEPH LEwIs, of Manchester, in the county of Lancaster, England,subjects of the Queen of Great Britain, have invented certainImprovements in Machinery or Apparatus Applicable to the Preparation andSpinning of Cotton, lVool, Silk, Flax, and Other Fibrous Substances; andwe do hereby declare that the following is a full and exact descriptionof our said invention that is to say:

Our improvements in machinery of apparatus applicable to the preparationand spinning of cotton, wool, silk, flax, and other fibrous substancesapply to those well known machines used in the preparation of cotton,&c., called slubbing frames and roving frames or jack frames and also tothose machines used for spinning` cotton &c., called throstle frame andto all other machinery used for twisting cotton, &c., whereon spindlesare employed.

Our invention relates solely to the spindle and flier employed in suchmachinery, the principal objects of the same being to increase theproduct-ive powers of such machinery by so forming and arranging thespindles as to allow of their being driven at a much higher velocitythan those hitherto in use.

Our improvements consist, firstly, in forming the spindle in twoseparate parts and connecting the two parts together by a jointorcoupling so that they may revolve together as one solid spindle andadmitting of the upper part being readily disconnected from the lowerpart when necessary; secondly, our improvements consist on fixing theHier permanently upon the upper part of the spindle; thirdly, in theemployment of a rigid bearing at the top of the spindle above the flier(in connection with the spindle formed of two parts) in addition to thebearings usually employed and fourthly, in making that portion ofthe-spindle bet-Ween the top bearing and the flier of a smaller diameterthan the part of the spindle forming the said top bearing so that whenthe upper part of the spindle is disconnected from the lower part andraised upward the upper portion of the said spindle can be held at suchan angle as will admit of the full bobbin being taken off the spindleand replaced by an empty one.

The practical application of our invention n will be betterunderstood byreferring to the drawing accompanying these presents and the followingexplanation thereof.

The drawing is made half-size and is marked with figures and letters ofreference corresponding with those in the description.

Figure l is an elevation of a slubbing spindle and iier in workingposition and Fig. 2 is a similar view with the upper part of the spindledisconnected and raised from the lower part showing the angle at whichthe upper part of the spindle may be held while doling the full bobbinand Figs. 3 id t are similar views of a throstle spin- The lower part aof the spindle is supported by the foot rail b and bolster or coppingrail c. The upper part cl, of the same being supported by the rigidbearing c, fixed to the roller beam of the machine. The upper and lowerparts of the spindle may be connected as shown in the drawing by a slipsocket oint, one part fitting in the other with a pin (l) on one eithera groove m in the other or by means of-a left hand screw or in any otherconvenient manner which will admit of the lower part driving the upperand of their being easily disconnected.V rIhe flier f, is fixedpermanently upon the upper part d, of the spindle by means of the pin g,or otherwise.

It will be seen that between the top part 7L, of the spindle which formsthe upper bearing and the flier j", the diameter of the spindle isreduced so as to form a neck z' of smaller diameter than the part h,which when raised allows of the upper part of the spindle being held atan angle whilst doffing as shown in Figs. 2 and l. It will also be seenthat the upper part of the spindle above the flier is formed tubular forthe passage of the cotton z-c.

Having now described the nature and object of our said improvementstogether with the method of carrying the same into practical effect wewould remark in conclusion that we are aware that a top bearing forspindles has been used although not in the manner or combination inwhich we employ it, we do not therefore claim the use or employment of atop bearing except for spindles formed or constructed as above describedbut IVe do claim as our invention The construction and application (tothe preparation and spinning of cotton &c.)

to be held at an angle While dofling the full bObbin, substantially asdescribed.
